It works for me (Firefox 82.0 @ Ubuntu). The only wish I'd have is to make it possible to enable/disable it on a per-site basis.

For the life of me I cannot get this add-on to work. On previous versions of Firefox there was one that worked well. I conduct a heck of a lot of research and one of these highlighters would be great if it worked and would save me a lot of time.

My Firefox for some reason stops to color visited link, I already made sure I am not in privacy mode, and 'Remember History' is turned on. And yes I tried to user other browsers, and they all worked, except for FireFox. I also did clean uninstall, then install fresh copy of FireFox, deleted profile folder to remove all preference, but nothing works. This addon is ONLY thing that color my visited link, because native Firefox on my Windows for some reason is broken. Thanks for making this addon!

Doesn't work at all. In Firefox preferences I set the visited link for red. Nothing. The links return to blue.
Firefox 78.1.0esr (64-bit)
2015 27" iMac

Modest functionality. More settings required: White list, black list, Individual settings for each site, Color selection.

Great add-on. I only wish it had a way to white-list specific websites. Hopefully future versions might have that.

The only one that worked for me. Awesome! Love it!

However, there is a problem. It works flawlessly on my desktop machine, but on my laptop, running the same Firefox 70 (64-bit) with the identical OS, it does not work. I removed and re-installed twice, to no avail. Please advise what I am missing. Thanks.

No configuration options whatsoever to be found, neither on the addons panel nor in any other icon.
The "default" color is some kind of dark purple, barely visible. Running FF 67.0.4.
Addon obviously deprecated, since it hasn´t been updated in more than 1.5 years.

Thank you. Now I can tell at a glance which Google search results I've already accessed and which I haven't. I research info across thousands (literally) of pages each year. The default colors between visited and not visited were near impossible to tell apart. Loading the same pages repeatedly while researching projects slows progress. Time saver you are :)

Could you please add button to toggle on/off ? cause some websites use the same or close background color.

This is great, this is great, this is great.

I love you dear developer.

I always had problem of remebering what links i opened/visited/read before.

Thank you very much.

Also had a question, in some websites i saw that this option in browsers may be used for extracting history by websites and privacy issues because of this reason.

Is this extracting my history by websites really applicable?

Although the convince of this addon unfortunately worth that privacy issues because the web really isn't usable for me without this :\

Update/ reply to another comment: Addon works on Android

=====================

Four Addons like this that are really great:

1. Visited link enabler (This Addon)
2. Gray visited links (use either this or that!)
3. Highlight bookmarks
4. Last visited Toolip

Hay que tener el historial habilitado para que funcione.

Installed today and it works just fine. No problems.

The extension installs but the icon does not appear in the tool bar, hence, I can't access the tool. I'm using Firefox 63

Thank you so much for this beautiful add-on. Would you consider making it work in Opera ? Thanks again.
Edited 01/11/18 - I noticed that at times the chosen
color doesn't work well with the colors of a particular website. Have you considered adding
a whitelist ? Best regards,

love it, thanks a million :D

Great but doesn't work framed websites (FF60.0.1)
and I want a white list option too.
